The resistance against water fluoridation might be a different story if the naturally occurring element of fluoride was added to our water. Fluoride is found in all natural waters, levels can be very high in groundwater, depending on a number of factors, such as the types of rocks and minerals of that region. Drinking water is the largest fluoride source.
Our tap water, on the other hand, is littered with hydrofluorosilicic Acid, a toxic industrial waste by-product that governments have been adding to our drinking water for over sixty years. Again, we’re not talking about the natural element of fluoride here, we are talking about industrial toxic waste.
Fluorosilicic acid regulation standard for use in water fluoridation is 98% purity. That's allows 2% arsenic and mercury from the hundreds of tonnes going into drinking water.
